EARRING-MACHINE.

To all whom t may concern:

Be it known that I, IVAN RoIC,a subject of theA Emperor of CroatiaAustria Huncounty of Cook, and State of Illinois, have invented certainnew and useful Improvekments in Barking-Machines,` of which` thefollowingis a specification.

My invention relates to improvements in barking machines adapted to'remove the bark from the sections of logs and has for its object theprovision of an improved conoperation.

The lnvention consists 1n the comblnations struction of this characterwhich Ihas efficient and arrangements of parts hereinafter de.

' partially in elevation, of a barking machine embodying my invention, n

Fig. 2, a ltransverse section ofthe same, and v Fig. 3,a top plan viewof the same. d The preferred form of construction as 'illustrated in thedrawings comprises an open work barking drum made up of a plurality ofsets of longitudinalangle irons 5 and 6 arranged to alternate with eachother wit-hone of their legs arranged circumferenvtially or on theperiphery of the drum and the other legs kprojecting at an acute angleinwardly with 'reference to the. peripher The upwardly projecting legs0f the ang e irons 5 are,l materially longer. than the correspondinglegs of the angle irons 6 .asy

shown. lthis arrangement the high points or roughprotuberances onthe los orv blocks to be treated will be treated by t e shorter legs of an leirons 6, whi1'e the main body or more uni orm portions thereof'are`simultaneously treated by the adjacent angle `irons 5, thus addinmaterially to the eHiciency of the machine. -The angle irons 5 and 6 arearranged to alternate with. each other and are secured in position bymeans of annular angle irons 7 riveted thereto, spaces being leftbetween said angle irons 5 and 6 to form an open workdrum to permit ofthe ready circulation of water therethrough. At intervals bearing rings8 are secured to the periphery of the drum between adjacent angle ironrings 7, saidv rings 4Specification of Letters Patent.

plane ofpthe barking drum, said'rollers 13 thus serving to partiallysupport the drum and also. to-.rpositlon the same centrally over`barking drum is provided shaft 1'0. he centrall vwith an annular gear15 secured to the periphery. thereof-between two of the annular angleirons 7, vsaid gear meshing with the pinion 16 secured to shaft 10.` Bythis arrangement it will be\ observed that .the barking drum isgiven asort of a floating bearing on the vat'vll. and may be rotated with theexpenditure of a minimum amount ofower.

The .-bar 'ngV drum is further stiHened `and strengthened by means ofVperipheral in the usual manner.

yThe vat 11 is providedr centrally with a depression or well 20 into;vwhich the removed and pulverized bark, fibers and particles'will bedeposited and an inclined trough or chute 21 leads upwardly and latmentit will be seen that the bark removedfrom the log sections will gatherand settle in the well 20 and will be removed therefrom by the .actionlof conveyer 22 inde endent of the actlon of the barking drum, t usaccomplishing such removal with great thoroughness and efficiency. Whendesired the well 2O may be readily drained and cleaned.-

While I haveillustrated and described the preferred form of constructionfor carrying variation and modification without departmy invention intoeffect, thisvis Capable of ing from the spirit of the invention. I,therefore. do not wish to belimlted to prev cise details of constructionset forth, but desire to avail myself of such variations andmodifications as come within the scope of the appendedclaims.

Having described my invention what I claim as new and desire to secureby Letters table drum having Walls thereof formed of longitudinal angleirons having one of their legs larranged circumferentially and the otherlegs projecting inwardly, and said inwardly projecting legs beingarranged lin alternating sets of differentheights, substantially asdescribed.

3. A barking machine comprising a vrotatable drum having walls thereofformed of longitudinal angle irons having one of their legs arrangedcircumferentially and the other legs projecting inwardly at an acuteangle, and said inwardly projecting legs being arr nged in alternatingsets of different heights, substantially as described.

t. A barking machine comprising a rotatable drum having' annular angleirons dening the circumference thereof, and longitudinal angle ironshaving oneof their legs secured'to the inner edgesA of said annularirons, the other legs of said longitudinal irons projecting inwardly atan acute angle, said inwardly projecting legs being arranged inalternating sets of different height-s, substantially as described.

5. A barking machine comprising a drum; supporting rollers positionedsubstantially centrally under said drum and contacting with theperiphery thereof; and positioning rollers on each side of said drumarranged to hold the same in position on said supporting rollers,substantially as described.

G. A barking machine comprising a drum; supporting rollers positionedsubstantially centrally under said drum and contacting with theperiphery thereof; positioning'rollers on each side of said drulnarranged to hold the same in position on said supporting rollers; andmeans engaging the periphery of said drum for rotating the same,substantiall)7 as described.

7. A barking vmachine -comprising any and carrying flanged rollersengaging said bearing rings; additional flanged rollers arranged onopposite sidesof said drum and bearing against said rings; an annulargear arranged centrally on said drum; and a pinion on said driving shaftmeshing with said annular gear, substantially as described.

8. A barking machine comprising an openwork drum made up of a pluralityof sets of longitudinally arranged angle irons secured together 'by'annular angle irons riveted thereto; bearing rings secured at intervalsaround the periphery of said drum; a driving shaft Varranged under saiddrum and carrying flznged rollers'engaging said bearing rings;additional flanged'rollers arranged on opposite sides of said drum andbearing against said rings; an annular gear arranged centrally on saiddrum; a pinion on said driving shaft meshing with said annular gear; avat` partially inclosing and supporting said drum and provided centrallyin the bottom thereof -with a `well; and an endless ch'ain conveyorleadingfrom 'said well, substantially as described.

9. A barking machine comprising an openwork drum made up of a pluralityof sets of longitudinally ar 'anged angle irons secured together byannular angle irons riveted thereto, said longitudinal angle irons beingarranged in alternating sets having inwardly projecting legs ofdlfferent heights; bearing rings secured at intervals around theperiphery of said drum; a. driving shaft arranged under said drum andcarrying flan ed rollers engaging said bearing rings; additional flangedrollers ar a-nged on opposite sides of said drum and bearing againstsaid rings an annular gear arranged centrally on said c rum; and apinion on said driving shaft meshing With said annular gear,substantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses. f
